Product Description
L-Theanine Benefits
L-theanine works as a nootropic by providing an increase in alertness and attention while still acting as a relaxing aging. Studies show that prolonged use of L-theanine can also be beneficial for memory, but the primary effects are utilized for short-term neurotransmitter alteration including increased GABA and serotonin.
Ample evidence proves L-theanine works synergistically with caffeine to negate the side effects while amplifying the benefits. Anxiety and jitters caused by caffeine are reduced by L-theanine supplementation. We provide an extra strength capsule that provides 200mg of 99% pure L-theanine per capsule. The benefits of sublingual solution is better and faster absorption that largely bypasses the first pass metabolism.
L-Theanine Dosage
The recommended dosage for L-theanine is as little as 100mg. The capsules are considered extra-strength in the the dosage is 200mg/capsule. However, the effects of L-theanine are felt in dosages as low as 50mg and young adults take between 50 – 400mg per day. The safety and low chance of toxicity allows for higher doses in some individuals. The average green tea drinker gets around 20mg of L-theanine per day.
Taking L-theanine with caffeine is effective with a 1 caffeine to 2 L-theanine ratio. With a regular 8 ounce cup of coffee, there are 100mg of caffeine suggesting 200mg L-theanine should be supplemented.
L-Theanine Mode of Action
L-theanine crosses the blood-brain barrier and increases levels of dopamine and serotonin the brain. It is also responsible for modulating AMPA, Kainate, and, NMDA receptors. The mode of action includes increasing GABA activity in the brain as well.
L-Theanine Toxicity
L-theanine has a high threshold for toxicity. Animal studies have shown no irreversible side-effects in rats with doses of 500mg / kg of weight. For a 150 pound individual, this equates to 34,000mg of L-theanine. However, headaches are a side effect of overdose in some individuals.

I’ve been taking l-theanine for several month to aide with my anxiety. I really like the sublingual solution you guys provide mainly because it is convenient to carry with me. I’ve been using the l-theanine as an additive to my coffee and it has been working well.

Since I need caffeine in the morning as a jump-start for my brain, I’ve begun taking L-Theanine with my morning joe (to which I add the Reishi Mushroom Powder, which I highly recommend. The quality of the reishi is excellent.), and it is just the right amount of stimulant without the jitters that I tend to get from coffee. I am also taking a cap at night before bed with magnesium, and it gets me to a calm state that allows me to fall asleep without any groggy, sedative-like feeling. I’ve noticed that I’m able to recall dreams more clearly as well.
